If we use the K.I.S.S. principle, then here is your formula: if your tree needs water, then water it. If your tree doesn’t need water, then don’t. Continue reading “Tree watering: a simple act, a science and an art, but bottom line – all trees need water (even in autumn)”
The Wisconsin Department of Natural Resources (DNR) and UW-Madison Division of Extension (UWEX) are partnering to better understand the informational resources available to professionals who provide tree care advice and services to urban residents in Wisconsin. Using information collected from an exploratory survey in early 2019, DNR and UWEX staff plan to improve access to these resources and address additional needs by creating new resources. Next steps include identifying a place where existing and new materials can be easily accessed by all audiences.
When asked to report the most commonly discussed topics with homeowners, pests and diseases emerged as the top issue (36% of respondents) with tree planting/care/selection or tree pruning as other popular topics (20-23% of respondents respectively). While 75% of respondents say that they use verbal advice to share information with residents always or most of the time, they also identified a diverse range of topics and types of content that they would find useful when communicating with their audiences.

Severe storms swept the northwest, northeast, and west central portions of the State from Friday, July 19th through the evening of Saturday, July 20th. The storms consisted of severe straight-line winds, large hail, heavy rains, and tornadic activity, resulting in significant tree damage on both public and private properties. Left unchecked, damaged trees can also result in major economic losses and create significant forest management problems. The DNR has been partnering with local municipalities to assist with recovery efforts by helping with debris removal.
In addition, the Department of Natural Resources, Division of Forestry has staff available to assist and connect you with the resources needed to mitigate the damages that have occurred from the recent storms. Depending on the situation, local DNR foresters may provide a property walk through, connect you with Cooperating Foresters and Logging Operators that work in the area, provide you with publications and information or direct you to federal resources such as the Natural Resources Conservation Service.

It’s another wet year in many parts of Wisconsin with water levels in lakes and rivers remaining very high. Seasonally wet areas are staying wet for longer, and areas that have not been wet for years are flooding or experiencing rising ground water levels. DNR forest health staff are increasingly noticing tree mortality due to these hydrologic issues. This occurs because flooding and high water reduces the amount of oxygen in the soil, depriving trees with submerged roots of the oxygen needed for growth and respiration. Along with submerged roots, trees can also die from uprooting and from subsequent insect and disease attack following flooding stress.

It may become necessary to conduct salvage harvests in flooded stands. Of course, the flooding also makes site access difficult. This is particularly concerning in stands where salvage harvests are needed to capture value, such as stands impacted by insects like emerald ash borer and eastern larch beetle.
Please let your local forest health specialist know if you are seeing flood-damaged stands. It is recommended to keep setting up salvage sales where appropriate. Access to wet or flooded sites can be difficult and may require frozen ground conditions if the site is expected to remain wet in the near-term.
Find your local forest health specialist on the DNR forest health webpage and learn more about flooding damage and mitigation with this resource from UW-Madison Division of Extension.

Forest health staff are again noticing health issues with white and bur oaks in 2019. A few trees with dieback in 2018 were recently resurveyed and were found to have recovered well. However, variable symptoms are appearing again in some areas. Forest health staff are conducting site visits to determine if the causal agents are the same as in 2018. Last year, leaf damage resulted from leaf fungal pathogens and twig damage was caused by Botryosphaeria fungi and gall wasps.
Please report any white or bur oak issues you notice to your local forest health specialist.

Fall webworm started showing up in early July. This native insect feeds on deciduous trees and shrubs and appears every year in yards and forests. Fall webworm forms loose webbing over branch tips. It can even completely cover a small tree with webbing. Inside the webbing you will find both live and dead caterpillars, partially eaten leaves and frass (caterpillar poop).

Fall webworm is more of a cosmetic issue than a tree health problem, but if people are concerned, they can take some simple measures to remove them. Open up the webbing using a rake, fishing pole, long stick or another long tool.. This will allow predators to get at the caterpillars inside. Or people can use their tool to roll up the webbing, peel away from the branch and place the entire web in a container of soapy water for a couple of days.
Insecticides can also be used to control this insect. If you decide to go this route, make sure the insecticide is labeled for caterpillars/fall webworm and that it will penetrate inside the webbing. With all pesticides, the user needs to carefully read and follow label directions.
As a native insect, fall webworm defoliation is unlikely to cause any harm to healthy trees. Use a control method described above if you are concerned about the aesthetics of a defoliated tree. Do not prune off the branch or burn the nest. Burning will cause more harm to the tree than the caterpillars will. For more information about fall webworm, visit this page from Michigan State University Extension.
The first step in campfire safety is to understand the difference between a campfire and a fire to dispose of debris. Campfires, solely for warming or cooking purposes, are smaller in size and comprised of clean and dry wood, contained within a designated fire ring or surrounded by rocks. Campfires are allowed anytime, except when Emergency Burning Restrictions are in effect. Burning in a fire ring with the intent to eliminate debris is NOT a campfire and does require a burning permit in DNR protection areas.
No matter what type of outdoor fire you have, check the daily burning restrictions for your area before ignition and never leave a fire unattended. Remember, you may be held responsible for all suppression costs and potentially any damages associated.
Cities, villages, towns, counties, tribes and 501(c)(3) nonprofit organizations in (or conducting their project in) Wisconsin are encouraged to apply for a regular or startup 2020 Department of Natural Resources Urban Forestry Grant! The grants range from $1,000 to $25,000, and grant recipients must match each grant dollar for dollar. A startup grant of up to $5,000 is available for communities that want to start or restart a community forestry program. Grants are awarded to projects that align with state and national goals for increasing the urban forest canopy and the benefits it provides.
Communities and organizations interested in applying for a 2020 Urban Forestry Grant may find the grant application informational video to be a valuable resource. It highlights priorities of the Urban Forestry program and discusses several other key aspects of the application process. The video is approximately eleven minutes long and includes topics such as the difference between startup grants and regular grants and how to contact an Urban Forestry Coordinator.
The application period opened July 1, 2019 and closes October 1, 2019. To view the application and informational video, visit the Urban Forestry Grant’s website. If you have questions regarding application process and eligible projects contact your DNR Urban Forestry Coordinator.
